| مصطلحات موضوعية: | TiO2 is the most frequently employed photocatalyst in realising complete mineralization of organic pollutants in water treatment.

Nitrogen doped into substitutional sites of TiO2 has shown bandgap narrowing and photocatalytic activity in the visible light. N-doped and non-doped mesoporous titania were synthesized using hydrothermal and ultrasound methods. Titanium-tetraisopropoxide was used as Ti precursor.
